Bloop f9effc2e18 Fixes some observer hard dels (#80757) ...

## About The Pull Request

Tin. This was another /image hard del that I came across within a given
round. AFAIK this was occurring because `updateallghostimages()` removes
refs of these images from GLOB.ghost_images_default and
GLOB.ghost_images_simple, and this proc was being called after
`QDEL_NULL()`. So they were still in the lists at the time of the
qdeletion. We don't need to be qdeleting them at all though so let's
just set them to null.
